Error "raise IOError(text)" when transfer file

[leafonsword]

my code is

from fabric import Connection
result = Connection('xx.xx.xx.xx').put('/tmp/wan.txt', remote='/tmp/')
print("Uploaded {0.local} to {0.remote}".format(result))

I got Error:

    raise IOError(text)
OSError: Failure 

And I found stackoverflow has gave the error:
Python paramiko SFTP IOError

I have the same problem @leafonsword, did you manage to overcome this ? Strange thing about my code is that it worked for months until one this started happening.

@mathiasbc I'm also waiting~

I had the same error. I'm using Fabric version 2.7.0 and I needed to transfer a file from a Linux host to a Windows host.
I tried the fix suggested on that StackOverflow question that @leafonsword attached here (which is basically specifying both the path and the desired filename on the remote host) but it did not work.
I had something like that:

conn.put("/folder/filename.extension", "c:/users/myuser/filename.extension")

I couldn't understand why it was not working. Looking at Fabric documentation regarding transfer it is mentioned an OSError error will be raised if a nonexisting local path is specified, but that was not the case.
So I started looking on how I could troubleshoot this error and I found this page. I enabled debug logging level as instructed there and I saw the following log:

DEBUG:fabric:Massaged relative remote path 'c:/users/myuser/filename.extension' into '/C:/Users/myuser/c:/users/myuser/filename.extension'

So Fabric is actually rewriting the remote path I specify!
The solution for me was omitting the remote path altogether, like that:

conn.put("/folder/filename.extension")

But this Fabric behavior does look like a bug. It should be looked into.

If paramiko failed to open the remote path /home/uos/inotify-info when put file,it will raise builtins.OSError: Failure
